My all-time favorite was the guy, and I remember hearing this one on network news, that decided to fly.
He got a six-pack of beer, a BB gun, a lawn chair and a bunch of surplus military weather balloons. He tied the lawn chair off to his truck bumper, filled the balloons with helium and strapped himself into the lawn chair with a belt. His theory being that he could float around for a while and drink his six pack, then shoot out the balloons with the BB gun, one at a time, and gently float back to earth.
Anyway, he cut the teather between the bumper and the chair, and the report said he ascended like he was shot out of a canon. Up to something like 10,000 feet. He freaked out so bad that he was afraid to shoot out any balloons and floated into LAX airspace, where rescue choppers couldn't retrieve him. He eventually (with an easterly wind) floated out over the Pacific. The Coast Guard helicopter attempted to drop a rescue cable to him several times, but the prop wash from the chopper kept blowing him away. A helicopter was finally dispatched with a super long cable, and he was eventually retrieved.
I love that one.
